Anyone in a similar situation?

Trying to conceive periods do weird stuff sometimes but last several months have been fairly normal and on time. I think I ovulated late this time around and I am currently 2 weeks late. Using pregmate pregnancy test strips since before I was late and still only negatives. I feel hormonal but I know that could be from period messing up. Mucus like discharge and yesterday even a little tinge of brown like old blood but only once and nothing since. Not sure what to think. Guess it's time to go to the doctor. 😔
